" The ancient observed, and we also observe, that sometimes things fall to earth, or some things leave the earth, or whatever parts we may be near. Whence, he says, and we may also say if we like, that something has moved either upward or downward, but only with regard to a certain region, or in a certain perspective, something passing from us to the moon would look the opposite to those across from us on the moon; where we would say, something has ascended, those moon people, our anticephali, would say that something has descended. Such motions, therefore, make no distinction between up and down, hither and thither with respect to the infinite universe, but only the finite world in which we are, or within the boundaries of the infinite worlds' horizons, or according to the calculations of the innumerable stars; hence, the same thing, with the same motion, can be regarded differently and called at the same time "rising" and "falling". Determinate bodies, therefore, do not have infinite motion, but finite and determinate calculation within their own limits. But that which is indeterminate and infinite has neither finite nor infinite motion, and knows no differentiation of space or time. "
